Under 46 CFR §58.25-10, the auxiliary steering gear must be capable of moving the rudder from 15° on either side to 15° on the other in not more than 60 seconds. This performance must be demonstrated with the vessel at deepest loadline draft and running at which speed?

Question

Accepted Answer

B. One-half maximum ahead service speed or 7 knots, whichever is greater — 46 CFR §58.25-10(d)(2) states the auxiliary steering gear must move the rudder from 15° on either side to 15° on the other in not more than 60 seconds with the vessel at deepest loadline draft and running at one-half maximum ahead service speed or 7 knots, whichever is greater. Option C reverses the 'greater/lesser' qualifier, making it a plausible but incorrect distractor.
